I bought these pliers to replace my old single ended safety wire pliers. Wow what a difference! I use them to screw bolts to our axle bolt and third element to our race truck. Sometimes the position of the bolt requires reverse rotation. I used to twist manually with pliers.... But that's no longer necessary. The pliers work smoothly in both directions. I also like the ratcheting effect when you bring the pivot back. I'm very happy with it!
